Arc flash hazard assessment for a 400-Hz system

摘要

In general, certain embodiments of the present disclosure provide methods and systems for determination and assessment of arc flash hazards at an equipment in an electrical power system operative at 400-Hz. According to various embodiments, a method is provided comprising determining an arc current at the equipment and generating an arc flash model based on the determined arc current. The method further comprises determining a value of arc flash incident energy by use of the arc flash model. In some embodiments, an arc flash protection boundary distance and/or a level of Prosomal Protection Equipment (PPE) are further determined by use of the value of arc flash incident energy for the equipment in the 400-Hz electrical power system.
